My friend had my favorite take I've heard on this: organizing to signal to the Democratic Party that Biden is in political danger because of his support of genocide (as Michigan did this week) is arguably more important than not voting for him in November, in terms of tangible impact on American policy. My personal goal is to put as much pressure on him as possible right now, and then I'll decide if I'm voting for him later this year based on how he responds.
Voting metaphors that don't have people dying in either option are disingenuous imo. Like I understand the concept of harm reduction to a point, but let's not pretend one of the options is something as innocent as "getting ice cream".
